Component Description: BCM
NOTE:
The BCM settings and configuration have no influence over the video signal from the camera. The camera provides a video signal any time it receives voltage and ground.
The BCM serves as a gateway module between the video camera and other modules on the HS-CAN1. It communicates with the video camera via the LIN and stores Diagnostic Trouble Codes (DTCs) for the camera and the LIN in the event of a concern.
